On some of my sites I have great problems with Admin Tools as I am very often locked out from backend and sometimes also from frontend. Very time I disable Admin Tools via FTP according the the guidelines, but when I then rename main-disable.php to main.php file, I am locked out again.
I am using a secret word in the url, and I have whitelisted my IP address.
Quite often I am only able to get access from my IP address, and if I try from another IP address, I will be locked out from backend and frontend.
I have followed all the guidelines as to the set-up, but how can I solve the problem?
